After two collapses, a third dam at ‘imminent risk of rupture’
A dam holding back mining waste from a Brazilian miner
is at risk of collapsing, a government audit says. The same
company was responsible for two tailings dam collapses since
2015 that unleashed millions of gallons of toxic sludge and killed
hundreds of people in Brazil’s southeastern state of Minas
Gerais, which has been known worldwide as the Brumadinho
Dam Collapse.
The retired Xingu dam at Alegria iron ore mine in
Mariana — the same municipality where a tailings dam collapsed
in November 2015 in what’s considered Brazil’s worst
environmental disaster to date — is at “serious and imminent risk
of rupture by liquefaction,” according to an audit report from a
local state organ. The report says the Xingu dam “does not
present stability conditions.” “It is, therefore, an extremely
serious situation that puts at risk workers who perform activities,
access or remain on the crest, on the downstream slopes, in the
flood area and in the area on the tailings upstream of the dam,”
the document says.
The ANM (National Mining Agency) rated the Xingu
dam’s safety at level 2 in a September 2020 assessment, after
requesting the company to improve the structure. The miner has
fulfilled part of the request, but has sought a deadline extension
for other repair works, without major changes in the structure. In
its most recent inspection, ANM identified structural problems
where no corrective measures had been implemented.

Based on the text above, judge the following item.
The text informs that the ANM has already checked on the Xingu dam, has requested the miner to improve the structure and has also fulfilled part of the request.

We can infer from the text that the dam which is at serious risk of collapsing is still working and may put its workers at risk too.

Can alternative tailings disposal become the norm in mining?
There is no doubt that the resources extracted from mining
are critical to our way of life. Likely, you’re reading this on your
computer, smartphone, or tablet. Mining touches all our lives
daily (in addition to metals used in electronics, think about that
can of soda you are drinking, or the aggregate used to pave your
driveway). The industry works hard to make sure the net impact
is positive.
However, the waste associated with mining, both past and
present, is an unavoidable result of conventional mineral
processing. In the future it may be possible to extract metals like
copper and gold without crushing and grinding the ore down to
fine particle size and adding considerable quantities of liquid,
resulting in conventional tailings.
What are the challenges associated with conventional
tailings? Well, it is all about water. Managing seepage from the
tailings themselves, monitoring pore water pressure within the
tailings dams or designing facilities to safely store or pass flood
events. Because such a significant quantity of water is added
during mineral processing, “conventional” tailings dams store the
tailings as a slurry. Water within the tailing material is either
evaporated, migrates as seepage or remains entrained within the
tailings impoundment. Removing water prior to disposal through
various means is considered “alternative” disposal. Mining low
grades of ore has resulted in increased water use per unit of
production. In some cases, the availability of water is one of the
greatest constraints on mine development.
